Types of Dc Motors and Dc Generator

What is magnetism? When two pieces of iron are attracted to each other by physical means or electrical means.

The magnetic field rotates 180 degrees when the battery slider moves from one side of the battery to the other.

The equivalent electrical circuit of a dc motor is shown in figure 5.2. It can be represented by a voltage source (Va) across the coil of the armature. The electrical equivalent of the armature coil can be described by an inductance (La) in series with a resistance (Ra) in series with an induced voltage (Vc) which

Generally, an electric motor is a machine which can transform electrical energy into mechanical energy. According to the power system, we can separate electric current flow into two classifications which are “Direct Current (DC)” and “Alternating Current (AC)”. DC and AC are two different forms of electric current flow, and they are provided and stored in different ways. For example, direct current can be provided by batteries or power supplies, and alternating current can be provided by sockets or generators. Based on using different types of power systems, there are two general categories of electric motors which are DC motors and AC motors. In addition, there are many different structures and functions of stators and rotors in the motor, so engineers develop different control theories to fit specific working situations. This paper is going to explain three control techniques in three aspects, illustrating how they work, exploring their advantages and disadvantages, and their

magnetic forces to make the motor spin. This way there is no combustion reaction that would

Brushless motors are a bit similar to normal DC motors in the way that coils and magnets are used to drive the shaft. Though the brushless motors do not have a brush on the shaft which takes care of switching the power direction in the coils, and this is why they are called brushless. Instead the brushless motors have three coils on the inner (center) of the motor, which is fixed to the mounting. On the outer side it contains a number of magnets mounted to a cylinder that is attached to the rotating shaft. So the coils are fixed which means wires can go directly to them and therefor there is no need for a brush. The reason why QuadCopters use brushless motors instead of normal DC motors is the much higher speeds and less power usage for the same speed. The brushless motors are more efficient as there is no power lost as there is in the brush-transition on the DC motors. Usually rated with a KV rating (revolutions per volt). This is not equivalent to torque, but lower KV motors are usually used for larger

The electric motors work by electricity and magnets working together. Once the electricity gets going, the magnets take over. The magnets keep the motor going because the magnets used in motors have both positive and negative magnets on both sides. Surrounding the magnetic ends, are one positive and one negative magnet. This means that at any

In a normal motor set-up, there are different mechanical and electronic components, for example, the admission complex, flash attachments, Mass wind stream/Volume wind stream, and so forth. Present day motors utilize the utilization of an ECM to give the best harmony in the middle of execution and emanations. Through the OBD correspondences convention, the electronically controlled parts of the motor can be altered in the process known as 'mapping'. Changing so as to map can either be performed the product inside of the ECU (chip tuning by means of firmware adjustment), or by giving false information through module equipment (piggybacking). Mechanical segments can likewise be supplanted, for example, turbochargers or

Magnetism is the physics phenomenon produced by the movement of an electric charge causing in an attraction and repulsion force between an object. A magnetic field can be created by an electronic solenoid and can be influenced by multiple variables. The number of coils on a solenoid will affect the strength of the magnetic field. Furthermore, the length of the solenoid will determine the strength of the magnetic field. As more current is passed through a solenoid the magnetic field will greaten. Current and voltage are propionate and as voltage increases, so will the current. Many variables may affect the strength of a solenoid, some of which are the number of turns wrapped and length of the rod.

This is the way the magnetic energy generator works in creating electricity. The fundamental understanding in mastering on how to generate cheap electricity is always that, like magnet rods repel one another while opposite rods attract one another. You will find some magnetic forces that are within the generator. These forces will push off against one another to be able to make the magnetic energy. Indeed if they could push against one another more, its keep is going to be a rise in producing magnetic

An electro magnet is a type of magnet in which a magnetic field is created by a current, in our case of the

Wind Power can be defined succinctly as the kinetic energy present in motion that can be converted to mechanical energy. The basic turbine uses mechanical blades that rotate due to the force of the wind to drive a generator that in turn sends electricity through a transformer into the power lines that supply energy to homes and businesses. The following diagram details the above-mentioned process1

The electricity from the positive and negative end of the battery and flows through the wire and makes the wire spin but you need to have the magnet for the wire to spin. You can change the way the wire spins but flipping the magnet over. The motor uses the attracting and repelling forces to make the wire spin. If you use stronger magnets the force will be greater. If you coil the wire more the magnetic field will get larger. But you cannot put to many coils in it or it will become too heavy. If you have wire with a coating you will have to scrap it off for it to work. If you put the support braces to far apart that can also become a problem. You can predict what way the wire or motor is going to spin.

Electromagnets can turn electrical energy into motion. Likewise the converse is true: they can turn motion into electrical energy.

Generator - The generator is similar to an electric motor, but it acts only to produce electrical power. It is used mostly on series hybrids. It is
